Analyzing Pressure Interference Between Horizontal Wells During Fracturing

During stimulation in fractured horizontal wells, offset well pressure measurements have been used to characterize hydraulic fractures. Past work has modeled this pressure interference between wells using static fractures as a proxy for fracture propagation. In this paper, we show that to accurately interpret the pressure response observed in a fractured monitor well during treatment of a nearby well, one needs to explicitly model the fractures and their propagation as a compliant discontinuity in the reservoir.
